Abstract

Cette invention se rapporte à un processeur d'informations, qui comprend un premier module de communication pour des communications de données sans fil. Un terminal informatique portable comprend un second module de communication capable d'établir une liaison de communication sans fil avec le premier module de communication. Ledit processeur d'informations est conçu pour indiquer un écran d'entrée de mot de passe uniquement lorsqu'une liaison de communication est établie entre le premier et le second module de communication. Les premier et second modules de communication sont compatibles avec le système Bluetooth. Ce processeur d'informations ne va démarrer le système d'exploitation que lorsqu'un terminal informatique portable enregistré est situé près du processeur d'informations et qu'un mot de passe correct est entré. Ainsi, on obtient un système de sécurité pour processeur d'informations avec double fonction de contrôle.
